Data Acquisition and Conversion/Getting Required Modules

Load the shapefile into QGIS to view and, in this case, simplify geometries due to the file size. To accomplish that in QGIS, select Vector -> Geometry Tools -> Simplify Geometries.

Next, using command line and in our working directory, convert the shapefile to GeoJSON using GDAL. In this case we entered:

ogr2ogr -f GeoJSON <output geojson> <input shapefile>

To create the application, we will define our dependencies in our package.json file:
